I lost the definition of friendship

Juz when i thought thing are getting better for us...u said something that are so hurtful. is this how we are going to go on?? while im reading it, i suddenly forget wat friend are for? r friends mean for you to insult, for you vent your anger? is that what you called cherish friendship? i tot we are becoming mature. i tot we r no longer childish as before. guess...im wrong. thats my wishful thinking.
